A new type of phosphor screen is presented,in which the aluminum film is replaced by the transparent conducting film as electrode. When voltage is added in the electrode coated with transparent conducting film,the electric capability of this new type screen is much better than that used ones. And the X-ray imaging tube with this new type phosphor screen can obtain higher space resolution. Additionally,this technique also has some other virtues,such as more easier in operation,low cost and high rate of finished product.
